Problems solved by technology

But it still has its disadvantages. First, it allows the header from the lower layer to be in plain text, so that the intermediate system can be relayed, but the disadvantage of this is that the encrypted data may be obtained by illegal users for illegal use; secondly, One shortcoming is that the concept of security level is defined in SCPS-SP but no specific use standard is given, so that the concept has not been practically applied

Embodiment Construction

[0039] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals designate the same or similar objects throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0040] Assume that there are two existing space users A and B who want to communicate, with A as the communication initiator and B as the communication receiver. The steps of communication between A and B are as follows:

[0041] Step 100: First establish a security association (SA), A sends a series of security level labels to B, and B selects one of them after receiving it, assuming that B chooses (1100 0001) to feed back to A, and A uses the security level labels fed back You can know the services to be provided (authentication, integrity, encryption) and some algorithm...

Abstract

The invention provides an SCPS-SP multi-security level and anti-replay function design method. Firstly, multi-security level design is provided according to a conventional space communication protocol specification-security protocol (SCPS-SP), different security requirements of users can be met by dividing different security levels, and then a method for achieving an anti-replay service in the SCPS-SP is provided. The abovementioned two types of design meet various security requirements of space communication users and enable security association negotiation among users to be convenient and simple; the anti-replay function is increased; and users are prevented from encountering a phenomenon that transmission information is intercepted by illegal users and is repeatedly sent to receiving users in a relay system, or transmission information is tampered or the like.

Description

technical field [0001] The invention relates to the improvement of the communication security protocol, especially the improvement method of the security protocol of the space data communication. Background technique [0002] At present, space information network communication has become a hot spot in domestic research in recent years, and space-ground-space integrated network is also an important trend of future network development. Compared with terrestrial communications, space communication systems have wider coverage, more frequent topology changes, and more vulnerable data during transmission. Therefore, it is very necessary and practical to propose a reliable and effective space communication security protocol. [0003] my country's existing space communication security protocol is the Space Communication Protocol Specification-Security Protocol (SCPS-SP) proposed by the Space Data System Advisory Committee (CCSDS). SCPS-SP can provide an end-to-end security protecti...
